Electrostatic discharge-safe ceramics, ESD-Safe ceramics, is developed to protect sensitive microelectronic components from static electricity buildup. This ESD-Safe ceramics can slowly dissipate accumulated electrostatic and senconary electron charges ---- preventing rapid discharge or arcing.
- The prepared ESD-Safe ceramic powder is pressed, sintered and the precision grinded, which makes the overall products is anti-static, to avoid the products loss of anti-static effect because of wearing;
- The surface resistivity of ESD-Safe ceramics is strictly controlled within the range of 106~108 ohms/sq;
- The ESD-Safe ceramics parts have good toughness and high bending strength;
- The products have excellent wear and corrosion resistance;
- The ESD-Safe ceramics parts have low thermal expansion and dimensional stability.
Typical applications of our ESD-Safe ceramic products include:
- End effectors
- ESD sensitive component handling
- Data storage components
- Data storage manufacturing tools
